spec does have a steel and aluminum option. I have the steel version and i like it. The steel flywheel weighs somewhere between 12 and 20 pounds i think. probably more like 17 or so roughly. Sorry i dont know the exact weight!!

^^^That's good to know that they make steel one.
Is it quieter than the aluminum? (chatter in neutral)

The stock SVT flywheel is ~25lbs, so if the Spec steel one comes in at 17lbs,
that's still a rather substantial "rotating mass" weight savings.

You sure you don't want to rip apart your tranny so you can weigh it for us? [:D] [eek]

spec sucks. just had another friend break a spec clutch. it was a stage 3 in a sr20 turbo 240sx that would hold allegedly like 450hp. his 250hp car broke it to where the car wont move in any gear. ive seen so many cars burn and break spec's that are WAAY under the rating spec puts on them. ill never buy anything from them. i drive mine like its stolen and i have had the stock luk non tsb replacement in it for about 15,000 miles with no probs.

steel is quieter than aluminum, but wont offer the same gains.

steel will offer the same gains. its all in what kinda driving you do. aluminum revs up faster due to less rotating mass, but what everyone doesnt understand is it rev's down faster too and takes the engine out of the powerband between shifts faster. aluminum only helps if your into auto crossing where you gas it and let out alot and gear down and up alot. if your into pulling out onto a straight and bangin thru the gears and just hauling ass billet steel is much better than aluminum.
